Merge branch 'ras-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RAS updates from Borislav Petkov:
"This time around we have in store:
- Disable MC4_MISC thresholding banks on all AMD family 0x15 models
(Shirish S)
- AMD MCE error descriptions update and error decode improvements
(Yazen Ghannam)
- The usual smaller conversions and fixes"
* 'ras-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
x86/mce: Improve error message when kernel cannot recover, p2
EDAC/mce_amd: Decode MCA_STATUS in bit definition order
EDAC/mce_amd: Decode MCA_STATUS[Scrub] bit
EDAC, mce_amd: Print ExtErrorCode and description on a single line
EDAC, mce_amd: Match error descriptions to latest documentation
x86/MCE/AMD, EDAC/mce_amd: Add new error descriptions for some SMCA bank types
x86/MCE/AMD, EDAC/mce_amd: Add new McaTypes for CS, PSP, and SMU units
x86/MCE/AMD, EDAC/mce_amd: Add new MP5, NBIO, and PCIE SMCA bank types
RAS: Add a MAINTAINERS entry
RAS: Use consistent types for UUIDs
x86/MCE/AMD: Carve out the MC4_MISC thresholding quirk
x86/MCE/AMD: Turn off MC4_MISC thresholding on all family 0x15 models
x86/MCE: Switch to use the new generic UUID API
